Merge tag 'dma-mapping-4.15' of git://git.infradead.org/users/hch/dma-mapping
Pull dma-mapping updates from Christoph Hellwig:
- turn dma_cache_sync into a dma_map_ops instance and remove
implementation that purely are dead because the architecture doesn't
support noncoherent allocations
- add a flag for busses that need DMA configuration (Robin Murphy)
